MACHINE FOR SPOOLING THREAD.

Specification of Letters Patent No. 27,012, dated January 31, 1860.

To all whom it may concern:

Be it known that I, C. M. SPENCER, of Manchester, county of Hartford andState of Connecticut, have invented certain new and useful Improvementsin Machines for Spooling Thread; and I do hereby declare that the sameis described and represented in the following specification anddrawings, and to enable others skilled in the art to make and use myimprovements I will proceed to describe the construction and operation,referring to the drawings, in which the same letters indicate like partsin each of the figures.

The machines heretofore used for winding thread on spools were providedwith a shaft to carry the spool, and a thread guide carried by atraverse rod with halfnuts alternately applied to a right and left screwto operate the traverse rod, so as to wind the thread on the spoolregularly from end to end in successive layers, the half nuts beingchanged by hand.

To make the machine automatic or selfoperating is the object of myimprovements; which consist in an arm connected to the thread guide, soas to be traversed and vibrated by it, so as to operate certain otherdevices, to change the half nuts at the proper time to reverse themotion of the thread guide,

Figure 1, is a perspective view of the machine with my improvements.Fig. 2 is an elevation of one side.

In the accompanying drawings A, A, are the ends of a cast iron stand orframe, one or both of which may be fastened to the base A with screws orotherwise. These stands are perforated for the ournals of the shafts,and other working parts of the machine, which ass through them.

B, is a sha t fitted to turn in the ends A, and is provided with apulley C, for the band which is to operate the machine. One end of theshaft B, is fitted to receive the spool 27, so as to turn with theshaft, and be easily and readily removed and applied; and the oppositeend of the shaft is provided with a conical pulley R, to carry the beltF, and turn the pulley Q, and right and left screw E, which is arrangedto turn in the ends A, as shown in the drawing. The pulleys Q, and R,are made conical so that the motion of the screw may be varied to suitthe size of the thread being wound.

H, is the traverse rod which extends through the tube H, which turnsfreely on it and is compelled to traverse with the rod by the nut is, onthe end of the rod. Both the rod H, and tube H traverse freely in theends A, A, and carry the thread guide D, and arm a, which are fastenedtogether, and both are made in the form shown in the drawing and fittedto turn or vibrate freely on the rod H, which is prevented from turningby the pin 71, which traverses against the pin g, in the end A, and thecoiled spring 6, is fastened to the rod H, and acts on a pin in thethread guide D, to press the end of the guide against the thread beingwound on the spool a. To traverse the rod and thread guide, the arms G,G, are fastened to the tube H, with half nuts near their ends fitted tothe right and left screw E, so that as the half nuts are alternatelybrought against, and released from the screw the rod and guide aretraversed alternately in each direction to wind the thread on the spoola. To rock the tube H and change the half nuts the arm J is applied tothe tube, which arm has a slide at, fitted to it and acted upon by aspiral spring shown in Fig. 2, which presses it out against the changingor vibrating block L, on the shaft K, which is fitted to turn andtraverse in the ends A, A, the end of the slide m, and the edge of theblock L, are both V-shaped, and the power of the spring 011 the slide issufiicient to press it, the slide m, out, after the block L, is vibrated(as will be hereafter described,) so that when the edge of the blockpasses the edge of the slide m, the spring on the slide forces. it outand pushes it down the inclined side of the block L, so as to turn thetube H, and throw one of the half nuts out and the other in to thescrew, and thus change the motion of the traverse rod. And as the layerof thread approaches the head of the spool, the arm a, strikes one ofthe arms N, and traverses the shaft K, so as to vibrate the block L, inthe opposite direction and carry its edge by the end of the slide m,pressing it into the arm J, until the edge of the block passes the edgeof the slide, when the spring forces the slide out as before mentioned,and changes the half nuts to reverse the motion of the transverse rod.

To operate the shaft K, and vibrate the block L, at the proper time tochange the nuts the block M, is placed on the shaft so the blocktraverses the shaft, by acting against the collars P, P, fastened to theshaft K, as shown in the drawing. The pin 0, is fastened in the end A,and extends through the block M, to prevent it from turning but allowsit to traverse. The arms N, N, are fastened to the block M, so that theymay be adjusted to such an angle as will suit or correspond with theheads of the spools used, and they are acted on by the arm a, on thetraverse rod H, so as to traverse the block M, and shaft K; and to givethis shaft a rolling motion the arm I, is fastened to it and its lowerend is fitted to traverse on pin 2', fastened in the base A at an angleof about forty-five degrees with the end of the base, so that as theshaft K, is traversed it is rolled or rocked to vibrate theblock L, andchange the half nuts as heretofore described.

To increase the length of traverse ofthe thread guide and adapt it tothe angles of the head of the spool 12, as it is filled with thread, thearms N, N, are arranged at an angle to each other as shown in the drawing, and the arm 0;, which acts onthe arms N, N, is fastened to thethread guide D, so that as the spool fills with thread it raises theguide, and gradually carries the arm at, out into the gradually wideningspace between the arms N, N, so as to increase the length of eachsuccessive layer of thread on the spool, and adapt it to the angles ofthe heads of the spool, so as to fill it uniformly from end to end untilit is full of thread.

To stop the machine when. the spool is full of thread the pulley C, isfastened to the shaft B, and the brake lever S, is arranged to vibrateon a pin in the end A, so as to act on the pulley C, when the left handend of the lever is dropped which is held up by the arm 0, of lever T,which lever vibrates on a screw in the base A and has an arm 03, whichextends up under the thread guide, so that when the spool is full, thethread lifts one end of the thread guide and depresses the other, sothat it strikes the end of the arm ol, and carries the arm 6, out fromunder the brake S, so that it falls and applies friction to the pulley Cand stops the machine; and a wire may be connected to the brake S, so asto release a clutch or change a band from a fast to a loose pulley atthe same time the brake is applied to the pulley C, and so that when thebrake is released the clutch or band may be changed back again tooperate the machine. When the brake S is raised to release the pulleythe spring j, fastened to the base A throws the arm 0, under the braketo hold it up.

To stop the machine'when the thread breaks or runs out before the spoolis filled with thread, the thread as it runs onto the thread guide isdrawn across the pins f, f, in the guide and under the hook e, from thelever a, which lever u, vibrates on a screw in the end A. Now so long asthe thread is drawn across the pins under the hook 6, it holds up thelever u, but when the thread breaks or runs out, it releases the hookand the lever falls, so that the opposite end strikes the arm 0, andpushes it from under brake S, so as to let it fall and stop the machineuntil the thread is mended or pieced up, and the machine started again.In order to allow the spool to make one or more turns at each end ofeach successive layer of thread the journals of the screw E, are turneda little longerthan the thickness of the ends in which it turns, so asto allow the screw a little end play, so that it may turn and traverseitself before it begins to traverse the half nuts, after they arebrought against it. The same thing may be effected by giving the tube H,a little end play on the traverse rod H.

I believe I have described and represented my improvements which makethe machine automatic or self acting so as to enable any person skilledin the art to make and use 7 them I will now state what I desire tosecure by Letters Patent, to wit:

I am aware that machines have long been in use for winding thread with ashaft to carry the spool-a traverse rod to carry the thread guideoperated by a right and left hand screw; with half nuts alternately ingear with said screw and changed by hand; therefore I make no claim tothese devices eXceptin combination with the devices which I have appliedto make the machine automatic or self operating.

1. I claim the arm 0;, in combination with the arms N, N, shaft K, arm Iand inclined plane or pin z', for the purpose of operating the block L,so as to change the motion of the traverse rod as described.

2. I claim the arm J, provided with a slide m, constructed so as tooperate substantially as described, in combination with the block L, forthe purposes set forth.
